摘要
钻孔灌注桩作为最常用的基础形式,适用于各种地质条件,该技术在理论和施工工艺上已经非常成熟,采用钻孔灌注桩工艺的缺陷桩虽然越来越少,但仍时有发生。论文针对桩底沉渣过厚的缺陷,通过实例,提出采用桩身取芯注浆补强的方法处理缺陷桩的桩底沉渣,经过实践取得了良好的效果。
As the most commonly used form,the bored pile applies to all kinds of geological conditions, its theory and construction technology have been quite mature, the defect of bored pile technology has been more and more less, but still occur occasionally. In the light of the defects of excessive sediment at the bottom of the pile, an example is taking in this paper to treat the bottom sediment of the defective pile with the method of coring and grouting reinforcement, and its effect is good.
